Additional Information Terms Aspect ratio Aspect ratio refers to the length to height ratio of TV screens. The ratio of a standard TV is 4:3, while the ratio of a high-definition or wide TV is 16:9. The latter allows you to enjoy a picture with a wider perspective. Bonus Group (DVD-Audio only) Some DVD Audio discs have a group which is known as the "Bonus Group" that can be accessed by inputting a 4digit key number. When attempting to play a Bonus Group, the key number input screen is automatically displayed. Playback begins once the key number has been input. Additionally, you can set the key number using the Setup screen General menu beforehand. Browsable pictures (DVD-Audio only) A feature of some DVD-Audio discs in which the user can browse still pictures recorded on the disc as the audio is played. See also Slideshow. Chapter number Chapter numbers are the numbers assigned to sections of a title on the disc, similar to chapters in a book. If the disc includes chapter numbers, you can locate the section you want very quickly using search and other functions. Component (color difference) video output The color signal of the TV is divided into the luminance (Y) signal and the color (PB and PR) signals and then output. In this way mutual interference of each signal is avoided. On a TV with component input jacks, these signals are synthesized to produce the picture. Condition memory "Condition" refers to the various mode settings, etc. On this player, various conditions, such as those set during playback, can be memorized. This function allows you to play back the same disc at any time without having to redo your preferred settings. Digital bitstream The bitstream does not refer to the audio signal, but rather to the digital data that, once converted, becomes the audio signal. The player outputs digital bitstreams via the digital optical or digital coaxial output. If the bitstream cannot be decoded by the connected AV amplifier etc., digital noise is produced. Digital bitstream formats compatible with different entertainment systems can be selected in the Setup screen Audio 1 menu. Digital output (Coaxial) Output of the digital audio signal is transmitted electronically using a coaxial cable. Because the signal being transmitted is digital, connection must be made to the coaxial digital input of another component. Noise will be output if connected to the analog audio inputs as the digital signal cannot be decoded. Digital output (Optical) Normally, audio is converted to an electric signal and transmitted through an electric wire from the player to the amplifier, etc. Changing this signal to a digital signal and transmitting it through an fiber-optic cable is called optical digital output. Similarly, optical digital input receives digital signals from external units such as an AV amplifier or receiver. DNR (Digital Noise Reduction) Digital noise reduction, in reference to video picture quality, refers to the detection and removal of digital artifacts, or errant video data, which appear as specks on the screen. When the digital noise reduction function of this player is on, some of this data can be detected and kept from appearing on the screen. Dolby Digital Using a maximum of 5.1 channels of audio, this high quality surround system is used in many of the finer movie theaters around the world. 1 DTS DTS stands for Digital Theater System. DTS is a surround system different from Dolby Digital that has become a popular surround sound format for movies. R Dynamic range Dynamic range refers to the difference between the maximum and minimum levels of the audio soundtrack as measured in decibels (dB). Compressing the dynamic range raises the minimum signal level and lowers the maximum signal level. This allows you to hear voices and other low level audio signals clearly while lowering strong audio signals like the sound of explosions. Group (DVD-Audio only) A collection of tracks on a DVD-Audio disc. Equivalent to a DVD-Video title. See also Title and Track. Interlace scan With interlace scan, the screen presentation is divided into odd and even scan lines. The first presentation (field) presents half of the screen . Before this image has faded from the screen, the other half of the presentation (frame) is displayed. The majority of TVs and monitors manufactured until recently have relied on the interlace scan system. In these operating instructions, the amount of interlace scan resolution is referred to followed by the letter "i" (for example, 525i). 71 En ADDITIONAL INFORMATION
